[summary of process]
Fig. 2 is the figure of the example of operation form for the display 35 to entry terminal 1 is schematically described.With reference to Fig. 2, in entry terminal 1, operator can input information with the right hand to display 35 can input information with left hand again.In fig. 2, hand 202 represents operator with the hand of operator during left hand input information and finger relative to the position of display 35.Hand 204 represents operator with the hand of operator during right hand input information and finger relative to the position of display 35.Operator if right-handed person, then mainly inputs information with the right hand to display 35.Operator if left-handed person, then mainly inputs information with left hand to display 35.
As intelligible from Fig. 2, when the right hand (hand 204) of operator inputs information to display 35, the finger used in input extends from the right side of display 35 to this display 35.Therefore, as a certain tendency in this case, the tendency pointed and contact with display 35 in the position that the point of wishing than operator is kept right a little can be enumerated.In addition, as other tendency in this case, following tendency can be enumerated: when the detection output of the touch sensor of display 35 can be subject to affecting of the finger of the position leaving display 35 or the position of stylus, the position that in fact touch location detected by touch sensor will touch than user offsets to the right.In addition, following tendency can be enumerated: now export in distribution in the detection of touch sensor than the part touched and produce deviation on the right side.Its reason is, the finger tip of the finger of user contacts with display 35, and refers to that abapical part is also being located with display 35 close on the right side than this contact position.In addition, the example of the touch sensor of above-mentioned impact can be subject to as detection output, such as, can enumerate the sensor adopting electrostatic capacitance mode or infrared mode as detection mode.
In addition, as intelligible from Fig. 2, when the left hand (hand 202) of operator inputs information to display 35, the finger used in input extends from the left side of display 35 to this display 35.Therefore, as a certain tendency in this case, the tendency pointed and contact with display 35 in the position that the point of wishing than operator keeps left a little can be enumerated.In addition, as other tendency in this case, following tendency can be enumerated: when the detection output of the touch sensor of display 35 can be subject to affecting of the finger of the position leaving display 35 or the position of stylus, the position that in fact touch location detected by touch sensor will touch than user offsets to the left.In addition, following tendency can be enumerated: in now distributing by the detection output leftwards at touch sensor than the part touched, produce deviation.
Fig. 3 is the figure of the defect caused of being shifted relative to the touch location of reality for illustration of the touch location detected by touch sensor.When (A) of Fig. 3 represents that the touch location of user itself is detected as touch location and is processed in entry terminal 1 or the desirable handwriting input to display 35 one routine.On the other hand, (B) of Fig. 3 represents when not carrying out this correction, to an example of the handwriting input of display 35 figure.
The degree of above-mentioned displacement is also subject in the impact proceeding the direction touching operator's moveable finger in input.Such as can enumerate when point move from right to left time shift amount less, when point move from left to right time the tendencies such as shift amount is more.That is, even if when drawing single line, when drawing curve etc., drawing the moving direction pointed in the process of line changes, then the amount of drawing above-mentioned displacement in the process of line can change.Therefore, as shown in (B) of Fig. 3, even if user is by the original track touch display 35 along word, the track that the track detected by display 35 touches from user is sometimes different.On the other hand, according to the present embodiment, if user is by the original track touch display 35 along word, then, as shown in (A) of Fig. 3, display 35 detects the track of its former state.
Fig. 4 schematically shows the figure of operator when using stylus to input information to display 35, to the example of the operation form of display 35.With reference to Fig. 4, in entry terminal 1, operator can utilize the stylus 210 pairs of displays 35 held by the right hand 208 to input information, and the stylus 210 held by left hand 206 also can be utilized to input information.Operator is if right-handed person, then the main right hand holds stylus 210 and inputs information to display 35.Operator is if left-handed person, then main left hand holds stylus 210 and inputs information to display 35.
In the present embodiment, judge that operator is by right hand input information to display 35 or inputs information with left hand.Then, entry terminal 1 carries out the adjustment of the displaying contents of correction and/or the display 35 exported from the detection of the touch sensor of display 35 according to this judged result.
As detecting the example of correction exported, can enumerate and such as make when being judged as right-handed person to be shifted to the left this correction by exporting the touch location determined from the detection of touch sensor.In addition, the degree of the displacement form of distribution that can export according to the detection of touch sensor and changing.Such as, sometimes, be judged as that the inclination of the finger of user or hand (stylus 210) is large, then strengthen shift amount.
As the example of the adjustment of the displaying contents of display 35, such as, can enumerate the adjustment of the icon arrangement of display in display 35.More particularly, the arrangement of adjustment icon, makes when being judged as right-handed person, and the icon utilizing frequency high is more arranged in right side, in addition, when being judged as left-handed person, utilizes the high icon of frequency to be more arranged in left side.
[detecting the example of mechanism]
The following describes in entry terminal 1, that hand that operate for detecting operator is the right hand or left hand mechanism.In this manual, sometimes will detect that hand that operator operates is that the right hand is called and detects that operator is right-handed person.Its reason is, if operator is right-handed person, then as a rule, this operator operates with the right hand.In addition, sometimes will detect that hand that operator operates is that left hand is called and detects that operator is left-handed person.Its reason is, if operator is left-handed person, then as a rule, this operator operates with left hand.
Fig. 5 is the figure of touch sensor detection to the mechanism of the operating position of display 35 for illustration of utilizing entry terminal 1.
In Figure 5, the cross section of touch sensor 40 is schematically shown.Touch sensor 40 comprises: glass substrate 40C; Electrode pair 40X, it is configured on this glass substrate 40C; And fender 40D, it is configured on electrode pair 40X.Electrode pair 40X may not be and is configured on glass substrate 40C but is configured on fender 40D.Touch sensor 40 is configured in face side relative to the display 35 of the state of a control etc. of display entry terminal 1.Thus, operator is via the display on touch sensor 40 visual identity display 35.In the present embodiment, expression utilizes display 35 and touch sensor 40 to form the situation of touch panel.
In addition, touch sensor 40 also can be configured in the rear side of display 35.In this case, operator, from the display of the surperficial visual identity display 35 of entry terminal 1, carries out touch operation to the back side of entry terminal 1.
Each electrode pair 40X comprises electrode 40A and electrode 40B.
The electrostatic capacitance of the electrode 40A of each electrode pair 40X and the electrostatic capacitance of electrode 40B change close to when each electrode 40A, 40B when electric conductor.More specifically, as shown in Figure 5, when (operator's) finger F of the example as electric conductor is close to electrode pair 40X, electrode 40A, 40B electrostatic capacitance separately changes according to the distance with finger F.In Figure 5, the distance of electrode 40A, 40B and finger F is represented respectively with distance RA, RB.In entry terminal 1, as shown in Figure 6, electrode pair 40X configures in the mode arranged in the whole region of touch sensor 40 (overlapping with display 35 in figure 6).Electrode pair 40X is by such as rectangular arrangement.In addition, in entry terminal 1, detect the electrostatic capacitance of electrode 40A, 40B of each electrode pair 40X independently of each other.Thus, entry terminal 1 can obtain the distribution of the variable quantity of the electrostatic capacitance of electrode 40A, 40B of electrode pair 40X in the whole region of touch sensor 40 (the whole region of display 35).Further, entry terminal 1 determines the touch location in display 35 based on the distribution of this variable quantity.
In addition, under the state that above-mentioned electric conductor does not contact with display 35 (touch panel), the electrostatic capacitance of each electrode 40A, 40B also can be subject to the impact of the position of this electric conductor (distance relative to each electrode 40A, 40B).Thus, the electrostatic capacitance of electrode 40A, 40B distribution according to such as illustrate with reference to Fig. 2, operator still can be affected by left-handed operation by right-hand operated.In addition, the electrostatic capacitance of electrode 40A, 40B distribution according to illustrate with reference to Fig. 4, operator to hold with the right hand or to hold stylus 210 and being affected with left hand.Fig. 7 with Fig. 8 be for illustration of in the distribution of the electrostatic capacitance of electrode 40A, 40B, the figure of impact that brought by the part do not contacted with display 35 (touch panel) of electric conductor.
In (A) of Fig. 7, represent in entry terminal 1 stylus 210 relative to display 35 not to the left and right in either party state contacted with display 35 obliquely.In (A) of Fig. 7, represent left and right directions with line L1.
In (B) of Fig. 7, represent the detection corresponding with (A) of Fig. 7 export in, an example that the detection of the electrostatic capacitance of the electrode pair 40X configured on online L1 exports.The longitudinal axis of the coordinate diagram of (B) of Fig. 7 is corresponding with electrostatic capacitance.Transverse axis is corresponding with determining the information (sensor ID) of each electrode pair 40X configured on online L1 respectively.The output E11 shown in (B) of Fig. 7 is corresponding with the electrostatic capacitance of electrode 40B.
Stylus 210 in entry terminal 1 is represented while tilt to the right relative to display 35 while the state that contacts with display 35 in (A) of Fig. 8.In (A) of Fig. 8, represent left and right directions with line L2.
In (B) of Fig. 8, represent the detection corresponding with (A) of Fig. 8 export in, an example that the detection of the electrostatic capacitance of the electrode pair 40X configured on online L2 exports.The longitudinal axis of the coordinate diagram of (B) of Fig. 8 is corresponding with electrostatic capacitance.Transverse axis is corresponding with determining the information (sensor ID) of each electrode pair 40X configured on online L2 respectively.The output E21 shown in (B) of Fig. 8 is corresponding with the electrostatic capacitance of electrode 40B.
In (B) of Fig. 8, output E21 reinstates the gentle gradient on the left of the ratio of slope on the right side shown in hollow arrow A21 from peak.Thus, in entry terminal 1, when electric conductor (stylus 210) is present in display 35 obliquely, the distribution that the detection of electrode 40A, 40B of touch sensor 40 exports also offsets to the side identical with this inclination.
Fig. 9 is the figure of distribution that exports of (such as rectangularly) respective detection of electrode pair 40X of configuring two-dimensionally in the whole region being shown schematically in touch sensor 40.In addition, represent that the detection corresponding with the state of (A) of Fig. 8 exports in fig .9.In entry terminal 1, as shown in Figure 9, the detection obtaining electrode 40A, the 40B of each electrode pair 40X configured two-dimensionally in the whole region of touch sensor 40 exports.In entry terminal 1, determine the position detected in the vertical direction existing for the peak value of output.Then, as shown in (B) of Fig. 8, the inclined degree of electric conductor is predicted in the distribution that the detection based on the left and right directions of determined position exports.
As described above, the relation of the distribution that entry terminal 1 utilizes the inclination of electric conductor and the detection of electrode 40A, 40B to export, and the inclination of above-mentioned electric conductor is predicted according to the distribution that above-mentioned detection exports.Then, based on the predicting the outcome of inclination of above-mentioned electric conductor, entry terminal 1 judges that operator inputs information with the right hand to display 35 or inputs information with left hand to display 35.
At this, illustrate according to the inclination with reference to the electric conductor illustrated by Fig. 2, the touch location detected by touch sensor 40 than actual touch location to the right or the tendency of left side displacement.
Illustrated by with reference to Fig. 5, the electrostatic capacitance of each electrode 40A, 40B of touch sensor 40 is subject to the impact with the distance of electric conductor sometimes.Thus, even if electric conductor does not contact with touch sensor 40, if there is electric conductor near touch sensor 40, then the electrostatic capacitance of electrode 40A, 40B is also likely affected.When operator inputs information with the right hand to display 35, predict the near surface at display 35, near the right side of the point contacted at finger or the stylus 120 of operator, there is electric conductor (right hand of operator).Original in the coordinate diagram shown in (B) of Fig. 7 or (B) of Fig. 8, the point that the peak value of electrostatic capacitance contacts with the finger of operator or stylus 120 is consistent.But it is contemplated that the near surface due to aforementioned display device 35 exists electric conductor, the state of affairs that the position touched is shifted to the right was wished from user originally in the position of this peak value.Such as, when right-handed finger operates, immediately below the place that user attempts touching is not pointed, and the situation being positioned at slightly left is more.But tripe is pointed at the center of the position contacted with touch sensor 40, therefore mostly peak is to be shifted slightly toward right.In addition, can expect, be also same when operator inputs information with left hand to display 35.

[check processing of touch operation]
Below, the content of the process for detecting the touch operation to display 35 is described with reference to Figure 11.Figure 11 is to detect the process flow diagram of the process that touch operation makes CPU20 perform in entry terminal 1.In addition, entry terminal 1 to accept under to the pattern of the touch operation of touch sensor 40 to continue to perform the process of Figure 11 in just during action.
With reference to Figure 11, in step slo, CPU10 judges whether to there is the touch operation to touch sensor 40.Then, CPU10 carries out standby till this operation being detected when being judged as not having touch operation, when being judged as there is touch operation, process is shifted to step S20.In addition, CPU10 such as illustrated with reference to (B) etc. of Fig. 7, is judged as there is touch operation the absolute value of at least 1 electrostatic capacitance in all electrode pair 40X becomes more than setting.
In step S20, CPU20 changes pattern to improve the sensitivity of touch sensor 40, and process is shifted to step S30.In addition, " improve the sensitivity of touch sensor 40 " to be realized by the raising of the integral number of times of such as sensing or the raising of quantity of information.The raising of the integral number of times of sensing can be enumerated, such as CPU20 is when the detection of 1 secondary amounts of each electrode 40A, 40B of each electrode pair 40X of decision touch sensor 40 exports, use the integrated value exported for 8 times from each electrode 40A, 40B, result uses its integrated value exported for 32 times of 4 times.The raising of quantity of information can enumerate the gain such as improving the detection from each electrode 40A, 40B and export in CPU20.
In step s 30, CPU20 makes process shift to step S40 after carrying out distinguishing of the state in the overhead (leaving the position on display 35 surface a little) of display 35.Distinguish and refer to and distinguish that electric conductor is tilted to the right in the overhead of display 35 or is tilted to the left as shown in (A) of Fig. 8.More specifically, the distribution that CPU20 exports as the detection of making each electrode 40A, 40B of touch sensor 40 illustrated by with reference to Fig. 7 ~ Fig. 9, and in the distribution that this detection exports, using detect export peak value as center when, according to be deflection right side (with reference to Fig. 8 (B)) or deflection left side distinguish that the electric conductor in overhead tilts to the right or tilts to the left.In addition, the testing result of the attitude of casing that the detection based on gyro sensor 39 exports, entry terminal 1 also can be used in the decision in direction up and down.
In step s 40, CPU20 is based on distinguishing that result decides to make process to step S50 transfer or makes process shift to step S60 in step S30.More specifically, if distinguish that result is that the electric conductor in overhead is tilted to the right in step S30, then CPU20 makes process shift to step S50.On the other hand, if distinguish that result is that the electric conductor in overhead is tilted to the left in step S30, then CPU20 makes process shift to step S60.
In step s 50, CPU20 is judged as that operator is right-handed person, and process is shifted to step S70.
On the other hand, in step S60, CPU20 is judged as that operator is left-handed person, and process is shifted to step S70.
In step S70, CPU20 makes the sensitivity of the touch sensor 40 be enhanced in step S20 get back to common sensitivity, and process is shifted to step S80.
In step S80, CPU20 performs the process (process of touch panel coordinate) of the coordinate figure of the operand of deriving in touch panel, makes to the processing returns to step S10.
In step S80, CPU20 can correct the coordinate figure (coordinate figure of the operand that the detection based on each electrode 40A, 40B of touch sensor 40 exports) of operand that determine based on the touch operation detected in step slo, touch sensor 40 based on the distribution of the testing result obtained in step s 30.The coordinate figure of the operand exported based on the detection of each electrode 40A, 40B of touch sensor 40 utilizes known technology to realize really surely, does not therefore repeat detailed description at this.In addition, as the concrete example of calibration substance, be " example that correct detection exports " by foregoing example.
The coordinate figure of deriving in step S80 is submitted to the application program of starting in entry terminal 1 by CPU20.Now, the judged result in coordinate figure and step S50 or step S60 can also be submitted to this application program by CPU20.Thus, this application program can carry out Change Example as comprised the contents processing in the application program of the displaying contents in the arrangement of as mentioned above adjustment icon etc., display 35 according to judged result.In addition, this application program also performs by CPU20 sometimes.
In present embodiment described above, in step s 40, when cannot distinguish electric conductor the overhead of display 35 to the left and right in which side tilt, CPU20 makes process to the side predetermined in step S50 and step S60, the transfers such as such as step S50.
[form of drive pattern change]
Figure 12 is the figure of the change of the pattern relevant with the change of the sensitivity of touch sensor 40 of the entry terminal 1 represented in present embodiment.In fig. 12, the sensitivity (transducer sensitivity) of the touch sensor 40 in the presence or absence (touch operation) of touch operation, the drive pattern (sensor driving) of touch sensor 40 and each drive pattern is represented.
With reference to Figure 12, drive pattern is standby mode, till the touch operation to touch sensor 40 being detected.When starting touch operation (process be equivalent in Figure 11 is shifted from step S10 to step S20), correspondingly, drive pattern distinguishes mode shifts to overhead, and the sensitivity of sensor (touch sensor 40) improves.In fig. 12, represent the sensitivity of the sensor before improving with " normally ", represent the sensitivity of the sensor after improving with " height ".
Afterwards, terminate the judgement of strong hand with the step S50 of Figure 12 or step S60, thus, overhead distinguishes that pattern terminates.Correspondingly, the raising of the sensitivity of sensor is removed.Afterwards, in during the touch operation of touch sensor 40 is continued, continue the detection (usual coordinate detection mode) of common touch location etc.Then, when touch operation is removed, pattern shifts to standby mode again.
Above-mentioned overhead distinguish pattern and usual coordinate detection mode also can during touch operation in alternately perform.Under overhead distinguishes pattern, be likely easy to owing to improving transducer sensitivity the impact being subject to noise.Thus, the positional precision of touch operation likely reduces, and therefore also can consider not use overhead to distinguish touching position information in pattern.But, it is contemplated that, only perform in during 1 touch operation and belong to overhead for 1 time when distinguishing process (the step S30 ~ step S60) of pattern, the decision of touch location likely cannot follow the change of inclined degree etc.Therefore, when this change cannot be followed, as long as alternately carry out overhead in during touch operation continues to distinguish pattern and usual coordinate detection mode.
[effect of embodiment and variation]
In present embodiment described above, when the touch operation of electric conductor (stylus, finger etc.) to touch sensor 40 being detected, discriminated operant person is right-handed person or left-handed person.Thus, comprise the displaying contents in display 35, the contents processing of application program can be corresponding with the hand (right hand or left hand) operated by user.In addition, this distinguishes to export based on the detection in order to detect the touch sensor 40 carried the touch location of display 35 and carries out, without the need to the sensor of its its special Do.In the present embodiment, operating body comprises the above-mentioned electric conductor to touch sensor input information.
In addition, in the present embodiment, the touch location (coordinate figure as touching object) of display 35 can be corrected based on the above-mentioned result distinguished.Thus, as explained in relation to fig. 3, the difference of the position that the coordinate figure of the touch operation obtained in entry terminal 1 and user wish can be reduced further.
In the present embodiment, during the strong hand (hand used in operation) of discriminated operant person in (step S20 ~ step S70), CPU20 improves the sensitivity of touch sensor 40.Thus, CPU20 can distinguish strong hand more accurately, and can detect its inclined degree.
By the raising of the sensitivity of touch sensor 40, the power consumption of entry terminal 1 can improve.But, in the present embodiment, only within above-mentioned period, improve sensitivity, suppress the raising of power consumption thus as far as possible.
In addition, owing to improving sensitivity, so comprise the possibility change of noise greatly from touch sensor 40 to the output of CPU20, thus, become large sometimes based on the error in the determined position of output of touch sensor 40.About this point, in preferably during step S20 ~ step S70, CPU20 based in the multiple electrode pair 40X included by touch sensor 40, the detection that is positioned at position and the neighbouring electrode pair 40X thereof touch operation being detected in step slo exports and performs process.In addition, above-mentioned error becomes large sometimes, therefore, does not use the positional information of the touch in the above-mentioned sensitivity raising time, and only distinguishes strong hand, obtain inclination information, thus the impact of this error can be fixed as Min..
In addition, as putting forward a highly sensitive example, enumerate the integral number of times of the detection output increasing touch sensor 40.In this case, CPU20, before obtain the detection output than usually many number of times from touch sensor 40, can not determine the detected value of each electrode 40A, the 40B in touch sensor 40.Thus, it is contemplated that the possibility that process is slack-off.In this case, in during step S20 ~ step S70, as long as carry out changing in the mode of the operating frequency improving CPU20 and touch sensor 40.On the other hand, in during in addition, by reducing the raising that operating frequency suppresses power consumption compared with during this period as far as possible.
Should consider that this time disclosed embodiment and variation thereof are example but not restricted contents in whole.Scope of the present invention is not by above-mentioned explanation but is illustrated by claim, is intended to comprise all changes in the implication and scope that are equal to claim.Disclosed in embodiment and variation thereof, technology is intended to implement as far as possible independently or after combination.
